Problems solved by technology

Generally, the pre-spinning coloring of dark textiles or engineering plastics is obtained by adding carbon black which is easily obtained as a pigment to the raw materials, but the problems of easily absorbing infrared light and causing its products to be rapidly increased in temperature are thus generated.
However, it is noted that the plastic films formed by most of the pigment compositions disclosed in the above patents and thermoplastic polyesters cannot maintain the original colors of the pigment compositions after the necessary processing of the textiles or engineering plastics (e.g. heating at 285-300° C.
); they must be further dyed after the products are formed, and the dark textiles (post-spinning coloring) or engineering plastics can then be produced such that the processing complexity and wastewater pollution are increased.

[Implementation Examples B1 to B32] Color Masterbatch Composition

[0027]The colorant was added to the pulverized thermoplastic polyester granules according to the content ratio of Table 2 below (95 wt % total), and 5 wt % of titanium dioxide was added, followed by extrusion at 240-280° C. in a twin-screw extruder. The mixture was kneaded to obtain the color masterbatch compositions of implementation examples B1 to B32.

[Application Example 1] PET Colloidal Particle

[0032]The color masterbatch compositions of the above implementation examples A1 to A32, B1 to B32, C1 to C32 and D1 to D32 were pelletized and then added to PET for color development (the color masterbatch composition accounted for 6 wt % of the total weight) to obtain the PET colloidal particles PETA1 to A32, PETB1 to B32, PETC1 to C32 and PETD1 to D32 of application example 1.

[Application Example 2] Fiber

[0033]The PET colloidal particles PETA1 to A32, PETB1 to B32, PETC1 to C32 and PETD1 to D32 of above application example 1 were drawn at 285 to 300° C. to obtain fibers FA1 to A32, FB1 to B32, FC1 to C32 and FD1 to D32 (the fiber fineness is 3 DPF) of application example 2, where fibers FA1 to A32 and FB1 to B32 are black, and FC1 to C32 and FD1 to D32 are dark grey, which can be suitable for dark textiles.

Abstract

A color masterbatch composition, comprising a thermoplastic polyester, a yellow colorant component, a red colorant component, and a blue colorant component. The yellow colorant component is selected from Pigment Yellow 147, Pigment Yellow 181, Pigment Yellow 183, Dye Brown 53, or a combination thereof. The red colorant component is selected from Pigment Red 122, Pigment Red 144, Pigment Red 202, Pigment Red 214, or combination thereof. The blue colorant component is selected from Pigment Blue 60, Dye Blue 67, or a combination thereof. The present invention further provides a colloidal particle that is obtained by developing the above masterbatch composition in a base material mainly composed of thermoplastic polyester. An article produced from the present disclosure has an effect of slowing down and reducing heat absorption and can maintain its original color during processing.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a color masterbatch composition, and more particularly to a color masterbatch composition for textiles or engineering plastics and an article produced therefrom.DESCRIPTION OF THE PRIOR ART[0002]Dark textiles are commonly used in clothing, curtains and sofas, and dark engineering plastics are widely used in electrical appliances and automotive components; they have a good shading and dirt avoidance. Generally, the pre-spinning coloring of dark textiles or engineering plastics is obtained by adding carbon black which is easily obtained as a pigment to the raw materials, but the problems of easily absorbing infrared light and causing its products to be rapidly increased in temperature are thus generated.[0003]Taiwan patent TW 1509038 discloses an infrared low temperature-rise pigment composition, capable of reducing the temperature rise caused by the absorption of infrared light by selecting specific pigments to co...
